Problems solved by technology

[0002] The equipped rims are 5.5F-16 or 6.5-16, which are generally used for tire-type hydraulic excavators whose overall weight is between 6 tons and 8.5 tons and the specifications of their driving tires are generally below 825-16. The driving safety performance of the excavator, so the brake device is an important construction machinery component. In the existing brake devices suitable for small-sized rims, only drum brakes can be used for braking. There are insurmountable defects in power, braking reliability, stability, durability, anti-aging, high temperature resistance and other aspects, which cannot meet the braking requirements of tire hydraulic excavators. Due to the limitation of installation space and the inability to directly install , disc brakes are not suitable for tire hydraulic excavators with 5.5F-16 or 6.5-16 rims

Abstract

The invention provides a brake device suitable for a small-specification rim. The brake device comprises a brake device body with an inner tong disc (1), an outer tong disc (2) and a cylinder body (3). A piston cavity body (12) connected with the cylinder body (3) in a containing manner and used for containing power liquid is formed in the inner tong disc (1) and the outer tong disc (2). The piston cavity body (12) is arranged into a round distortion cavity body with a contour line with a long axis and a short axis, and the long axis of the contour line of the piston cavity body (12) is arranged to stretch along the peripheral line of the inner tong disc (1) and the peripheral line of the outer tong disc (2); and by means of the cylinder body (3) and the piston cavity body (12), transversepush hydraulic acting force is generated to the cylinder body (3), braking force is generated by the cylinder body (3), the situation that only a drum brake is adopted for braking does not exist anymore, and therefore a disc brake still cannot be suitable for a tire type hydraulic excavator with a rim of the 5.5F-16 or 6.5-16 specification.

Description

technical field [0001] The invention relates to a brake device, especially a brake device suitable for small-sized rims. Background technique [0002] The equipped rims are 5.5F-16 or 6.5-16, which are generally used for tire-type hydraulic excavators whose overall weight is between 6 tons and 8.5 tons and the specifications of their driving tires are generally below 825-16. The driving safety performance of the excavator, so the brake device is an important construction machinery component. In the existing brake devices suitable for small-sized rims, only drum brakes can be used for braking. There are insurmountable defects in power, braking reliability, stability, durability, anti-aging, high temperature resistance and other aspects, which cannot meet the braking requirements of tire hydraulic excavators. Due to the limitation of installation space and the inability to directly install However, disc brakes cannot be applied to tire hydraulic excavators with rims of 5.5F-1...
